ABSTRACT
A combined bivalent alhydragel vaccine against both duck plague virus [DPV] and duck virus hepatitis [DVH] was prepared. The efficacy of the new vaccine was evaluated in different groups of ducklings compared with a single vaccine against each virus alone. Evaluation depended upon estimation of both humoral and cellular immune response. The prepared combined vaccine offered a high titre against each virus. Obtained results have shown that the antibody titre obtained with the new vaccine are never inferior to the titres obtained with the separate single vaccine
